这个分为be动和助动.(一般现在时)
be动:Iam,weare,youare,theyare.例如,Weareclassmates.
be动变成一般疑问句时就是把be动词提前,我们换成你们,其它照抄,例如,Areyouclassmates?
助动就是需要助动词do来帮助完成否定句和疑问句的.当主语是I/we/you/they时,动词用原形.例如,Ithinkmilkisgood.WecomefromChina.Youdohomework.Theycleantheroomeveryday.
变成一般疑问句就是:Do+主语+动词原形+其它成分?
例如:Doyouthinkmilkisgood?DoyoucomefromChina?Doyoudohomework?
Dotheycleantheroomeveryday?
希望能帮到你啊~
